Abstract : Electrical energy demand in Ethiopia has been enormous in past years as a result of economic growth and development. Hence, more efficient use of energy must be considered as one major option to achieve sustainable developments. The goal was to assess the degree to which energy-saving bulbs(CFLs) are being used in target area and to determine luminous efficiency of bulbs used by customers. Data was collected using questionnaire, interview and laboratory experimentation and analyzed using logistic regression, percentages and correlations. It was revealed that only 57% of customers included in the sample were users of energy saving bulbs and probability that a customer uses CFLs is significantly affected by monthly income and understanding towards energy saving strategies. Correlation coefficient between number of CFLs and monthly income was found to be R = 0.362. A customer with average monthly income and with understanding on how to save energy is 7.48 times more likely to use CFL than a customer with the same monthly income but with no understanding. It was found that average luminous efficiencies of CFLs and non-CFLs were 12.369% and 2.554% respectively. If all bulbs used wereCFLs, then 1335996 KWh per year could have been saved.

Keywords : Correlation, Luminous Efficiency, Logistic Regression, Odds-Ratio.
